Xcel Energy is a partner in CapX 2020, a joint initiative of 11 transmission-owning utilities in Minnesota and the surrounding region to expand the electric transmission grid to ensure continued reliable service. The new transmission lines will be built in phases designed to meet electric growth, as well as to support renewable energy expansion. For more information on the projects, please visit www.capx2020.com. 

The State of Minnesota has adopted a biennial transmission planning process to ensure the integrity of the state’s electric transmission system. A complex network of transmission lines transmit electric energy from electric power generating plants to local distribution substations and to other utilities in the region.

Transmission-owning utilities in Minnesota file a biennial transmission planning report with the Minnesota Public Utilities Commission in the fall of odd years. These utilities have joined to sponsor the Minnesota Electric Transmission Planning and public meetings concerning transmission issues so that the public can become more directly involved in planning.
